Reflective display device using anisotropic optical film

摘要

[Problem] To provide a reflective display device with excellent white color (having a feeling of paper white) that is free from glare or bokeh, and that can display high-quality paper-like white when white is displayed. [Solution means] A reflective display device comprising a reflective plate and an anisotropic optical film whose linear transmittance varies depending on an incident light angle, wherein the anisotropic optical film is disposed on a viewing side of the reflective plate rather than the reflective plate, and the anisotropic optical film comprises at least , an anisotropic light-diffusion layer, wherein the anisotropic light-diffusion layer has a matrix region and a plurality of columnar regions having different refractive indices from the matrix region, wherein the plurality of columnar regions are formed from one surface of the anisotropic light-diffusion layer. A reflective display device comprising: being oriented over the other surface and having an average major axis/average minor axis and an in-aspect ratio of the plurality of columnar regions on one surface of the anisotropic light-diffusion layer of 20 or less.
